Any decent 1.5-4.5x or 1.5-6x if it was me.
458 should be a <200 yard rifle and to me the wider field of view is far more important than high magnification on dangerous game unless you prepare to use it on varmint during off season![]()
A nice 2300fps 450 grain hollow point ammo on a groundhog should get the littl bugger killed, skinned, cooked and burried in one step. Basically vaporize the little bugger with no mess left to clean up. It's a win win
